It's not looking good. Neither Kobo nor BooksonBoard has answered my email requests for information about publishing through them. However, a writer colleague sent me a copy of the guide that Kobo (after a long delay) sent her, and if that's any indication, then Kobo is not even remotely set up to deal with authors in a user-friendly way. As for BonB, who knows?

Does anyone know if the Apple store permits territorial restrictions, if one uploads directly? (I haven't, to date, because they require an Apple device for doing the upload, but that's probably something I could finesse.)

I wonder how hard it would be to set up a storefront on my own site. (Well, I know it's theoretically not that hard to set up a shopping cart, but to manage geographical restrictions and automatically handle payments and downloads...)
